Nintendo of Japan’s president, Tatsumi Kimishima talked briefly about the NX with the Nikkei newspaper. According to Kotaku, the Nikkei asked Mr. Kimishima what kind of game machine the NX is. He replied:
At this current stage, I’m not able to say. However, it’s not merely the successor to the handheld 3DS or stationary console Wii U. This will be hardware that’s been made with a new way of thinking. I’d like to announce more particulars regarding its specs and how it works another time this year.
When pushed as to why the NX isn’t releasing in time for the busy holiday season, Kimishima explained that there needed to be software ready to go along with the NX. While not official, it could be that a marquee title like the new Zelda game wasn’t going to be ready for release by this holiday and thus the decision was made to push the system out to March of 2017.
Mr. Kimishima also said that the Wii U production would end in the future, but gave no specific timeframe only saying, “Since we are making a big shift to the NX, there is that possibility (in the future).”
As of now, Nintendo is planning on unveiling the NX later in the year, presumably sometime between September and December. No word on if it will be a major press event like Sony held for its unveiling of the PlayStation 4, or if Nintendo will utilize a Nintendo Direct to present the new platform to the masses.
